[0025] The structure of the mold for an automotive interior door handle provided by this utility model is as follows: Figure 1 , Figure 2 as well as Figure 3 As shown, it includes a rear mold assembly 1 and a front mold assembly 2. The rear mold assembly 1 and the front mold assembly 2 cooperate for the injection molding of the inner door handle. The front mold assembly 2 includes a hot runner plate 21, a front mold assembly 2, and a front mold core 23. The bottom of the hot runner plate 21 is fixedly connected to an A plate 22, and the front mold core 23 is installed inside the A plate 22. The top of the hot runner plate 21 is equipped with a panel 211 with a positioning ring. The surface of the hot runner plate 21 and directly below the panel 211 is a hot runner system. The hot runner system of the hot runner plate 21 has a cavity inside, which is connected to the injection channel. The front mold core 23 has a hot nozzle inside, and the bottom of the channel is connected to the hot nozzle.

[0026] During implementation, the injection molding machine uses a positioning ring to position the injection material. After injection, the material flows into the hot runner system cavity of the hot runner plate 21 and then flows out through the hot runner into the hot nozzle of the front mold core 23.

[0027] Furthermore, such as Figures 4 to 9 As shown, the rear mold assembly 1 includes a base plate 11, a B plate 12, and a rear mold core 13. The top of the base plate 11 is fixed to the B plate 12 by a screw, and the rear mold core 13 is installed inside the B plate 12. A first sliding insert 4 and a second sliding insert 40 are slidably connected to one side of the interior of the rear mold core 13. A groove 41 is provided on the side wall of the first sliding insert 4 and the second sliding insert 40. The groove 41 is a flow channel for the injection of glue. The interior of the groove is used to flow the glue. A sprue groove 3 is provided inside the groove 41. After the front mold assembly 2 is closed, the hot nozzle communicates with the top of the sprue groove 3. The surface of the front mold core 23 is provided with a limiting groove 7, and the top of the sprue groove 3 after the rear mold assembly 1 and the front mold assembly 2 are located inside the limiting groove 7. The surface of the B plate 12 and one side of the first sliding insert 4 are slidably connected to the sliding seat 5 through a wear-resistant plate. The first sliding insert 4 and the sliding seat 5 are fixedly connected by a screw. A scraper 6 is provided on one side of the sliding seat 5. The scraper 6 is connected to the sliding seat 5 through an inclined guide post, and the scraper 6 is fixed to the surface of the A plate 22 by bolts.

[0028] During implementation, when the rear mold assembly 1 and the front mold assembly 2 are closed, the shovel 6 pushes the slide seat 5 to squeeze the first slide insert 4 under the action of the inclined guide rod. When the first slide insert 4 moves, it will drive the sprue groove 3 inside the groove 41 to move to the side of the product cavity.

[0029] Working principle: When the rear mold assembly 1 and the front mold assembly 2 are closed, the shovel 6 pushes the slide seat 5 under the action of the inclined guide rod, which drives the first slide insert 4 to move and reset. After the rear mold assembly 1 and the front mold assembly 2 are closed, the sprue groove 3 is connected to the hot nozzle inside the front mold core 23. During injection, the injection molding machine is positioned by the positioning ring. After the glue is injected, it will flow into the hot runner system cavity of the hot runner plate 21, then flow out from the hot runner and enter the hot nozzle of the front mold core 23, then enter the sprue groove 3, and finally enter the mold cavity to complete the injection.

[0030] This invention designs the sprue groove 3 on the first slide insert 4, and designs a groove 41 on the first slide insert 4 to hold the sprue material and keep it on the rear mold assembly 1. This achieves the effect of holding the runner through the groove 41 of the slide insert, preventing the front mold assembly 2 from pulling the sprue material and bringing it to the front mold assembly 2 during subsequent mold opening, thus preventing damage to the product's appearance. At the same time, the unique design of the sprue groove 3 allows the glue to be injected on the side of the handle, which solves the problem of injecting glue on the appearance surface without damaging the handle's appearance.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
